Point 2 does not make sense. Attack speed will always increase DPS--at any given time or situation.
Point 3 is also strange as it is hard to believe you can shoot 5 or 6 elemental arrows within the window of 1 second. Not realistic with current level of gear.
For his(her?) point 2, the point was that at a constant dps, a higher ASPD means more time shooting hungering arrows. This is because you spend your hatred faster shooting EA (or whatever your spender is), which means you're empty sooner, which means you have to refill sooner. +ASPD gear does increase your dps, but their may be a point where the faster spending of hatred results in less DPS over some period of time because you're spending more time using HA than you would be with less ASPD.
For point 3, its not that he fits in 6 shots from first hit to 1 second, its that he shoots six shots by the time the first one hits, so all the ones already in the air have 100% crit chance.

This could just be what was available at the time, but i've checked repeatedly and it seems to hold true.
